The cost to replace the cambelt and water pump on a 2017 Fiat Ducato 2.3 MultiJet II is reported to be £630 for the cambelt alone, with a full service added bringing the total to £2,100 at a professional garage. Independent garage estimates for similar models range from £435 to £485, while franchise dealers may charge between £626 and £724, depending on the year and parts used. These figures include parts such as the timing belt, water pump, idler pulley, tensioner, and o-rings, with some DIYers saving £200–£250 by performing the work themselves. The 2017 model is subject to the same maintenance schedule as other 2.3 MultiJet variants, with recommendations to replace the timing belt every 4 years or 120,000 miles, whichever comes first, and to replace the water pump at the same time if it has been in service for several years.
